Me too, i have the same problem on PS4, when i tried to apply skin back to defaultI do have it but I apparently can't apply it to my ships.
I think cmdrs on ps4 who managed to grab it before the last update probably have it in their livery but can't apply it. As for those of us who didn't grab it then, it does not appear at all.
As of now, Monday morning, I still don't have my paint jobs on any of my ships.
CMDR's please tell me I'm not losing it here:
OUTFITTING - LIVERY - PAINT JOBS ??
